For the moment 1 will do.
Now I've got to figure out the following:
A) How many shots I can fit onto a 32gb card over a 12hr timelapse at max resolution.
B) How to keep the camera powered for a full 12 hrs to do the timelapse - especially as my only power sources will be either 1) spare batteries or the battery back pack or 2) Airplane in-seat power supply, so may be able to trickle charge the battery.
I would think tht if you're doing a 12 hour timelapse in an airplane, that you would be able to power down and swap out batteries without any impact on the timelapse, especially if this is at 35K feet over the Atlantic. This might be the easiest solution, assuming that you can do this without removing the GoPro from its mount and changing the framing/camera angle.
Just a thought.
